The following reaction goes to completion: 2NO(g) + H2(g) ⇌ N2O(g) + H2O(g) + 340,270J

What would be the effect on the reaction rate if the hydrogen gas concentration were doubled?

If the pressure on the reaction were doubled?

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
